In this lecture, a fast overview of the formalism used in Nuclear Magnetic Resonance is provided, with a stress on the density matrix approach. Its equivalence to the classical derivation for particular spin systems is shown. The different interactions which are usually encountered are introduced. Finally, the case of randomly time-dependent interactions inducing relaxation is addressed.
